■ Detailed information
• This function is used with heat pump and heat recovery.
• The fan rpm is reduced by about 50 to 70% and may vary depending on environment and logic.
• Differences between SE9 and SE11
- SE9 (Noise Reduction): outdoor unit noise control + indoor unit noise control
- SE11 (Heating fan Low noise): outdoor unit fan noise control
(control factor : the outdoor temperature, heat exchanger temperature, indoor unit operation rate,
not always controlled)
ex) In case of SE11, optimize fan noise by adjusting the target low pressure when
the outdoor temperature is more than 5℃, the indoor unit operation rate is less
than 30%, and the heat exchanger temperature is more than 3℃

■ Detailed information
• This function is used with heat pump and heat recovery.
* Note : In order to prevent the accumulation of ice on the side of the outdoor unit, it is considered
that the number of partial defrost is minimized and that overall defrost is effective on the
outdoor unit side. however, on the indoor unit side, frequent overall defrost can cause the
lack of heating (according conversion to cooling cycle).
